The Study
Endothelial CD36 Mediates Diet-Induced Increases in Aortic Stiffness
This study looked at mice, not people, and found that when scientists turned off a specific protein (CD36) in their blood vessels, the mice didn't get as stiff as other mice on a junk-food diet. But that doesn't mean the same thing happens in humans — we can't say this protein causes stiffness in people.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
When mice eat a high-fat, high-sugar diet, a protein called CD36 in their blood vessel lining sucks in too much fat, which makes the arteries stiff and sick.

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1This suggests that blocking CD36 in humans might help prevent stiff arteries caused by unhealthy diets, which are a major cause of heart disease.
- 2Deleting CD36 in blood vessels reduced artery stiffness by 29%, lowered fat buildup in artery walls, improved blood vessel relaxation, and reduced inflammation.

High blood sugar levels trigger chemical reactions that produce harmful compounds called advanced glycation end products, which make tissues stiffer and increase inflammation throughout the body.
In female mice eating a high-fat diet, removing CD36 from blood vessel lining cells reduces inflammation in the aorta by maintaining occludin protein levels and lowering the presence of immune cells and inflammatory signaling molecules.
In female mice eating a high-fat, high-fructose diet, removing CD36 from blood vessel lining cells reduces aortic stiffness by 29% and decreases vascular insulin resistance, fat buildup, leakiness, and inflammation.
In female mice fed a Western diet, removing CD36 from blood vessel lining cells results in improved blood vessel relaxation in response to two different chemical signals, showing that both major pathways controlling vessel dilation remain functional.
In female mice eating a high-fat diet, removing CD36 from blood vessel lining cells stops the buildup of lipids in the aorta and reduces lipid transfer to surrounding muscle cells.
In female mice fed a high-fat, high-sugar diet, removing CD36 from the lining of blood vessels stops the thickening and scarring of the aorta.
